Justin Rose says switching to a Novak Djokovic-style gluten-free diet is the reason behind his turn in fortunes - including a second-place finish at last week's Masters.
Rose has endured a miserable start to the year, but finished on 14-under at Augusta on Sunday, four shots behind champion Jordan Spieth - a score that would have been enough to win all but two green jackets since the turn of the century.
Despite the disappointment of missing out on becoming the UK's first Masters champion since Nick Faldo in 1996, Englishman Rose says he is "feeling better than ever before" thanks to the tennis world No.1's eating regime.
"I have given up gluten, like Djokovic. It worked for him - he is a little whippet," Rose said. "I reckon I have lost eight to 10 pounds and I feel so much better for it.
"My joints feel amazing, no soreness, no early morning creaks. It has been amazing. I'm still training and still lifting in the gym and have kept my strength up. It's just the unwanted stuff that's disappeared."
Rose has missed three cuts so far this year, while his tie for 37th at the Houston Open a fortnight ago his best finish before the Masters. And he hopes his fine week in the season's opening major will kick-start a run of good form.
"There's two ways to look at it," he said. "You can think that I shot 14-under and I'll take that next year and the year after that and take a lot of confidence from that, but you've got to play it on the day, too.
"I felt like there were moments in which I could have done better and I'll learn from those moments and think about them.
"But overall, I was happy the way I stuck with it, and to come here with not a lot of form so far this season, to finish tied second [with Phil Mickelson] is obviously a good result. I feel like my season is now under way."
Rose makes no secret of the fact that, since breaking his duck at the US Open two years ago, he is concentrating on the majors and the Ryder Cup.
He added: "You look at Rory's year last year, it was all about how he played in the summer. And [when he was missing cuts] I kept telling myself it's a long year and that this year for me is going to be about April to September, when the big tournaments come around, and that's when I want to play well.
"I'm very happy it turned around this week at a major, but the thing that was most important for me was the fact I have not been in contention this year and did not have any positive vibes on which to draw. So I was really pleased at how comfortable I felt in that situation, playing last group in the Masters on Sunday. That makes me very hungry to get there again very soon."
World No.8 Rose will play in the Classic of New Orleans next week before the WGC-Match Play Championship in San Francisco and the Players Championship at TPC Sawgrass.
